Some people think that “Climategate” will ultimately undermine everything that the UN is attempting to resolve in Copenhagen, but that story is for a later column. The truth, however, is that the parties – all of whom profess agreement that man-made global warming is a reality – are doing a powerful job of self-destructing outside the scientific controversy. The divisive issue is, as expected, which nations will bear the costs necessary to deal with climate change, and how those costs will be apportioned. Judging from yesterday’s conflicts, it seems that even those who agree that the problem exists are in gridlock over financing its solution.
